Section 4. Setting up Datalogger Networks

When the device is contacted on a schedule, communication with the device

will be terminated once this time limit is exceeded. A value of 0 in this field

indicates that there is no time limit on maintaining a connection to the device.

When the device is connected in the Connect Screen and the time limit

approaches, a dialog box is displayed warning the user that Max Time On-Line

is about to be exceeded. The dialog box has

Reset Max Time and Don’t Reset

buttons. If the

Reset Max Time button is pressed, the Max Time On-Line

counter will be reset. If the

Don’t Reset button is pressed or if no button is

pressed, the connection will be terminated when Max Time On-Line is

reached.

The format for this field is 00 h(ours) 00 m(inutes) 00 s(econds).

If you are using LoggerNet Admin or LoggerNet Remote 4.0 and

using the Connect Screen to connect to a remote server that is

running an older version of LoggerNet, the behavior will be

different than described above. When connecting to a LoggerNet

3.4.1 server, you will be disconnected with no advanced warning

when Max Time On-Line is reached. A message will be displayed

indicating that Max Time On-Line has been reached. When

connecting to servers older than LoggerNet 3.4.1, the behavior

will be variable. Generally, you will be disconnected at some

point, but the timing of the disconnect will not be predictable.

Attention Character – Enter the character that will be used to reset the RF400

modem. By default, the radios are programmed to use the + character as the

Attention Character. However, if the RF400 is being used in a

communications link that includes a phone modem, you will most likely need

to change this character in the RF400 radio setup and on LoggerNet’s Setup

Screen. Most phone modems use + as the reset character, and sending this

character unexpectedly will reset the modem and terminate the

communications link.

Advanced
Maximum Packet Size – Data is transferred in “chunks” called packets. For

most devices the default value is 2048 byes. The value entered in this field can

be changed in 32 byte increments. If a communications link is marginal,

reducing the packet size may improve reliability.

4.2.4.15 RF400 Remote

This device is used to set up the RF remote in a point-to-multipoint RF

communication network containing CSI’s RF400 modems. It has only

Hardware and Notes tabs.

Standard
Communication Enabled – Before communication can take place, all devices

in the chain must be enabled. When this box is selected, the RF400 radio is

enabled for communication.
